ANDREW EPPLER, OF LYNN, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATE RSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

BOUNDI NG AND GHANNELING MACHINE.

Application filed July 1, 1911.

To all whom it may concern:

Be it known that 1, ANDREW ErrLnR, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Rounding and Channeling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to rounding and channeling machines which are em ployed to operate upon shoe soles after they have been incorporated in boots and shoes.

The invention is intended more especially as an improvement on the Goodyear rough rounding and channeling machine shown and described in the patent to French and Myer, 599,609., February 22, 1898, although it is not confined in its application to this ma chine but may be embodied with advantage in other forms of rounding and channeling machines. Machines of this class are employed for rounding the edge of the sole and cutting a channel in the surface of the same. after the sole has been incorporated in the shoe and preparatory to the sewing operation. In addition to the above described operations, it is oftentimes essential to perform still further operations upon the sole, such, for example, as beveling the margin of the sole at the shank in order to form a light edge shank, which operations have heretofore been performed separately from the rounding and channeling operations.

The object of the present invention is to enable such a further operation to be per formed conjointly with the rounding and channeling operations and without interfering with the speed or accuracy of these lat ter operations. I

With this end in view a feature of the invention consists in the combination in a machine of the character described of an auxiliary knife for skiving the margin of the sole and rounding and channeling knives for trimming the edge and cutting a channel in the surface of the sole, respectively.

A further feature of the invention c0ntemplates the provision in a rounding and channeling machine of an auxiliary knife arranged tooperate upon the sole, and which may be thrown into and out of operation Specification of Letters Patent.

during the continuous operation of the rounding and channeling knives.

Still further features of the invention comprise certain novel features of construction, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be apparent to those skilled in the art from the following description.

In the accompanying drawings illustrating the preferred form of the invention, Figure 1 is a view showing a detail of the side elevation of a rounding and channeling machine embodying the several features of the invention in their preferred form and illustrating the auxiliary knife in an inoperative position; Fig. 2 is a view similar to Fig. 1 and illustrating the auxiliary knife in operative position; Fig. 3 is a view showing a detail of the front elevation of the rounding and channeling machine; Fig. l is a longitudinal section taken upon the line 4-4 of Fig. 3; Fig. 5 is a detail illustrating an elevation of the sole supporting spindle and channeling knife mounted thereon; Fig. 6 is a detail sectional view taken on the line 6-6 of Fig. 4; and Fig. 7 is a plan View of the supporting plate for the sole support illustrating the mechanism for clamping the channeling knife in position.

In the machine shown in the drawings, 1 indicates the trimming knife, 2 the Work support or crease guide, 3 the feed plate, 4- the forepart gage, 5 the channeling knife, and 6 the vertically movable sole support on which the channeling knife is mounted. In order to cut the channel nearer to the edge of the sole along the fore part than at the shank, the forepart guide t is mounted upon the end of a supporting arm 7 which is pivoted at 8 to the machine frame and is provided with a depending bracket 9 adjustable in and out on the arm 7 and which carries a shoe 10 upon its lower end. The channeling knife 5 and sole support 6 are mounted upon a vertically sliding frame 11 which is provided with a rack 12 formed upon one face. An oscillatory toothed segment 13 engages with the rack and is operated by a curved lever 14: having an arm 15 which engages with the shoe 10 so that upon a downward movement of the arm 7 a slight upward movement in a vertical direction is imparted to the sole support and channel ing knife. The sole support-6, as indicated clearly in Figs. 4: to 7 inclusive, consists of an anti-friction roll ournaled on a vertical spindle 18 which is supported upon the slid-' out of the way in order to remove the roll. and adjust the channeling knife. All of the above described parts have the same construction and mode of operation as the corresponding parts in the Goodyear machine above referred to and are only briefly described herein in consequence thereof.

In the illustrated embodiment of the invention, a skiving knife is provided which follows the rough rounding and channeling knives in their operations upon the sole and which may be thrown into and out of operation at the will of the operator during the continuous operation of these knives. This skiving knife is employed for beveling or skiving the margin of the outsole at the shank in order to form what is termed a light edge shank, thus imparting a better finish to the shoe and enabling this portion of the sole to be more readily operated upon in the subsequent leveling operation.

In the simplest and most eificient form of the invention which has yet been devised, the beveling knife is normally arranged in operative relation to the sole and is automatically moved into an inoperative position upon the downward movement of the forepart guide into engagement with the shoe. Thus the movement of the beveling knife into and out of operative position is effected at the proper time without necessitating a slowing down of the machine or in any way hindering or changing the action of the rounding and channeling knives. In the construction illustrated, the auxiliary or shank beveling knife, as it may be termed, is indicated at 25 in close proximity to the channeling knife 5 and arranged to follow the channeling and rounding knives in their action upon the sole. The knife 25 is adjustably supported upon the upper end of a curved arm 26 in order that it may be moved toward and from the channeling knife as desired. The arm 26 is pivoted at 28 to the lower end of the sliding frame 11 in order that the auxiliary knife 25 and the channeling knife 5 shall have the same vertical movement, thus insuring that the beveled surface shall extend from the edge of the sole to approximately the base of the channel flap, as shown clearly in Fig. 2 of the drawing. The knife 25 is normallyretained in operative engagement with the work by a compression spring 30 which is interposed between the rear face of the arm 26 and the frame of the'machine. In order to automatically move 'the'knife out of engagement with the work upon the downward movement of the forepart guide into operative position, a dog 31 is mounted upon the lever 14: and is arranged to engage with a stud 32 projecting from the arm 26. Thus upon an oscillatory movement of the curved lever 14 due to the downward movement-of the arm 7, the'dog 31 engages with the stud 32 and rocks the arm 26 against the action of the spring 30 to remove .the knife 25 from engagement with the work. In order to regulate the depth of the cut of the knife 25, an adjusting screw 33 is threadedly mounted in the lower portion of the arm 26 a and has its free end engaging with'one face of the frame 11. The adjusting screw 33 is locked in anyadjusted position-by a locking nut 34:.

WVhile it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood that this construction and arrangement is not essential except so far as specified in the claims and maybe varied or modified with out departing from the broader features of the invention.
